SMA Solar WebConnect

jbviperrr · December 8, 2020, 7:12pm

your integration will be ok, but are you getting all the readings from the SMA?

hunkyn · December 8, 2020, 10:41pm

When I login in the SMA webconnect portal and I do see daily_yield values and few others. Some I could not find when I login as a user.

jbviperrr · December 9, 2020, 9:13am

I logged in as installer and put the tcp server “on”. After doing so i could use them all. Try to get that code from the company that installed yours or ask them to do it for you

hunkyn · December 9, 2020, 4:39pm

Updated the TCP and tried with user and installer accounts and I still do not see these values. I will keep researching and see if I am missing something from my end.

hunkyn · December 9, 2020, 8:55pm

I tried using the modbus option and i do get daily yield but that is a very long number as others have mentioned. Hopefully there is a fix for that and my setup for SMA is complete.

jbviperrr · December 10, 2020, 9:22pm

I use this and never had any issue. Hope this helps for you. keep me posted if it did

Yes. I am using the same one. But for Daily Yield I get a very large number as others above have mentioned.

I have been looking into this more and the register 30517 is not a valid value for the version in US and that could explain why this random value. I looked into the sunny web portal and seems like it is calculating based on the 5 minute intervals it gathers data from the TotWh (30513) register and displaying in the UI. I am not sure how I go about adding the date parameter to this sensor and do the calculation to make it happen. This way we can calculate Today, Yesterday and daily generation from SMA.

juiced · December 16, 2020, 10:16am

Not sure if you’ve been able to fix it already, but i had the same and it was solved after i’ve updated the firmware of my Sunny Boy

hunkyn · December 16, 2020, 2:31pm

I have the same issue and I am on the latest firmware as well but it is not resolved.

MathieuWuyts · July 26, 2021, 5:14pm

Hi all, I’m new to the hassio scene.
Main reason I’m getting in to it is our SMA solar installation. I’m trying to use the SMA integration that’s included, but can’t connect to our home manager. Can anyone tell me to where I should connect as the ‘host’? Tried ip adress and serial number, but I can’t seem to connect. Is there a setting I should change in the home manager or something?

Bimbo009 · October 28, 2021, 7:50am

Hi, I have tried to follow your example, but I got this far and then it’s over for me now it’s about the sensors that I can’t call up and always get an error message.
Maybe something is wrong with the settings in the inverter.

devUBi · February 11, 2022, 2:58pm

@csacre I used your very nice sma_bridge AppDeamon class and it was working perfectly since a few days. It seems that SMA changes sommething at there Sunny Portal website. Is your’s still working? or maybe can you share an adjustment, if you already did one?

csacre · February 12, 2022, 7:29am

Even if I am using modbus now, a lot better, I tried my legacy integration in AppDaemon and it still work. I only tested the part that is getting data from the portal. Could you be more specific ? MAy be an error in the AppDaemon log ?

devUBi · February 14, 2022, 6:54am

I have put some log output inside the getSMAData to see the result of the request:

…
response = session.get(url,headers=myheaders)
if response.status_code == 200:
myhtml = response.content
self.log(“myhtml:” + str(myhtml))
…

And the problem is, that there is no more json returned but the html page. Seems that maybe the login did not work anymore, even if it tells " INFO sma_bridge: SMA Logon :200 ".
Maybe you have any idea where to look for?

csacre · February 15, 2022, 7:16am

@devUBi

On my side, I still receive JSON data so it works.
So it may be location dependent (I am in Belgium)
If you see the data in the HTML page, it wold be anyway possible to parse the content.
Do you see the production data in the HTML page ?
If you send me a copy of the data, I can parse this and update the code.

dibummer · February 15, 2022, 12:13pm

Hello,
I state that I have several gaps with English and moreover I am a novice in the use of home assistant.
I come to the point, I configured in my configuration.yaml file what was reported by mamra andreas, it seems that it does not give me any errors; however I cannot find the way to view the inverter information from the home assistant; someone tell me how to do it?
by the way, the inverter is Sunny Boy TL6000-21 and is installed in Italy.
thank you

devUBi · February 16, 2022, 7:12am

@csacre
I did some more debugging and traced out the content of the response after the login around here:

self.log (“SMA Logon :” + str(response.status_code))

The result is an html page with the login page again and above user and passowrd field the message:

Unknown e-mail address or incorrect password

So i copy and pasted the login data from the script to the real website and tried to login and it was working - so login data in the script is correct.
I don’t know what happens. Maybe they are blocking something.

csacre · February 16, 2022, 11:31am

Did you changed your password ? Do you have special characters in your password ?

devUBi · February 16, 2022, 11:53am

no nothing special, no change

csacre · February 16, 2022, 8:37pm

So far I tested locally on my PC. I created a test class to run in from AppDaemon4 and still working.
Do you use AppDaemon4 ?

Do you have beautifulsoup4 in the packages for AppDaemon4 (configuration) ?
I am getting out of ideas.
